I appreciate the current enthusiasm in crypto markets and the resilience it has shown with the crash a few weeks back.

However this is my warning that there is a high chance of a black swan that will upend things.

Specifically in terms of regulation & exchanges. The SEC has sent a warning shot but it seems to have been brushed off by everyone in short order. But what's happening now with Bitfinex goes beyond the surface. I suspect a major US exchange is likely to have major problems shortly.

And the biggest risk of all is not actually the SEC -- but the PBoC. The Chinese government has yet to take enforcement action on ICOs and it remains fairly easy for Chinese to purchase crypto. However new ICOs are being launched in China at a crazier pace currently than even in the west at the moment (most of which you haven't heard about). The PBoC are well-aware aware and will do something soon - I suspect again it may involve the more "retail" exchanges which will put an enormous damper on sentiment.

They have even more incentive given they've cracked down on just about all other major sources of capital outflows. And the ramification will be enormous - let me tell you, when the Chinese (or Koreans) panic & dump a speculative asset, there's quite nothing like it.
